I'm looking for a set of pistons for my sleeved 84mm LS block with B16 head. I'll be running 91-93 octane so the compression has to be managable. I'll be tuning with Crome Pro.

On the Arias website, I found part number #3330511 for the B18 and B20 which offers 11.8 compression:

On the Wiseco website, I found part number #K567M84 for the CRV/VTEC which offers 11:3 compression:

Which of these do you recommend for a daily driver or what are you guys using on your 84mm LSVTECs?

Personally, I'd go with an Arias or a JE. Not speaking from direct experience with an LS-Vtec, but I have used their products in other motors and they are

. Weiscos aren't bad... but they are definitely a price point line.

I don't understand "price point line"

Wiseco But this has been covered

Price point line = The manufacturer you want to have in your store for more cost-conscious customers. Basically cheaper shit. Sun-pro to Autometer, Weisco to JE, Eagle to Carillo.

LOL, I hope you are not implying that wiseco is cheap shit compared to JE. There is nothing about a JE piston that makes it "special" or sets it apart from the rest.

I think you have something backwards, Im not even going there.

OP just check the posted link of what some of the more informed guys are saying. It doesnt matter if its an LSVtec or not all pistons would work the same in a GSR.

The weight, they are like bricks.

7rrivera7 · 01-03-2007, 03:38 PM

Thanks NA for the link...I'm pretty much decided on Wiseco. Now, for 93 octane, 84mm bore, the Wiseco's available show 11.3 compression. Is this enough for Skunk2 Pro 1's and ITBs?

not really.....look at the off the shelf piston specs for the same bore piston at roughly the same compresison.......they are pretty close if not the same.

JE part number: 189681 81mm 8:1CR 268 grams
Wiseco part number: K541M81 81mm 8.6:1CR 268 grams

JE part number: 253036 81mm 11:1CR 282 grams
Wiseco part number: K566M81 11.5:1 275 grams

so they must both be bricks then.........how much lighter do you want? an extra few grams from one piston brand to another doesnt mean squat.....it's the qualitly that important.

JE get my vote......always has and now always will.

SOHCinWA · 01-03-2007, 05:26 PM

If you call Arias and talk to Tom Jung he can tell you just about anything you need to or want to know. They have many different pistons choices (ratios) on the shelf. And you can run at least 12.5 to 1 if you are running an aftermarket ignition setup aswell.

ExospeedAMcrx · 01-03-2007, 11:49 PM

to get an idea. this is the exact 84mm piston from Arias that you were looking at pt#3330511

ComeOnKip · 01-04-2007, 05:24 AM

Trust me, I see alot more SBC and BBC customers having minor to major issues with weiscos then any other piston I sell. I'm not saying every weisco piston made is bad, I'm just saying that JE and other lines have better quality control, less customer complaints, etc. I know people make some crazy numbers on weiscos, but my money would put a JE or Mahle in my motor.

99hondacura · 01-04-2007, 02:21 PM

yea how much r the arias pistons as opposed to the wiseco? which r better?

bambam · 01-04-2007, 02:46 PM

I would steer away from Arias for all motor apps.
Stick the the lighter weight offerings from wiseco and CP.

and why is that? you have experience with all those brands?

92TypeR · 01-04-2007, 03:46 PM

CP pistons here, and we have used them in almost all of our builds. Tight build tolerances and they have a new line of lightweight pistons. They are very quiet for a forged piston, unlike JE.

I would run 12:1 or even 12.5:1. You can get away with compression above 12:1 when running large cams like Pro-1's. But I would rethink your ITB idea, unless you plan on running a tunable setup like Jenvey's, stick with a plenum.

Don't have to. Their chemical makeup tells me enough. Arias pistons are some of the hardest pistons out there. With that, they expand the most too. That is something you want more for a turbo piston. Not to mention, Wiseco and CP have some of the tightest clearances - where it's important.
They are also the heaviest, when compared to the same or similar compression ratios to other piston manufacturers - Wiseco, JE, CP - another argument that they are GREAT for turbo, but less than ideal for all motor.

Don't get me wrong, it's not about failure rates or anything like that. You have to do something terribly wrong to detonate one of those pistons or have it fail elsewhere. Arias manufactures a VERY good piston. If I was a turbo guy, I might even choose to run them. But, I recommend Wiseco and CP to all my customers and friends for the reasons stated above.

Thanks guys...this has turned into a very interesting thread

I have a set of TWMs. Will it be a nightmare to tune via TPS instead of MAP?

TWM's make sh*t for power on 2.0L's, especially when using a PR3 head. A set of TWM 50mm's made 1 more whp peak and a max of 4whp in the midrevvs over my stock ITR TB/IM on my 12:1 85x87.2 setup. We have even seen a loss of power everywhere on a 2.1L B-series compared to a ported JG VictorX.

If you want to make power, look into a ported ITR IM like the Import Builders, or a ported JG VictorX.

TWM's were R&D'd on a mild 1.8L using a P72 head, only use them on similar setups. If you are dead set on ITB's, Jenvey's offer separate castings for P72 and PR3 heads, along with numerous velocity stack combinations for tuning, and spacers for valve-to-plate tuning.

7rrivera7 · 01-05-2007, 01:08 PM

Damn...what to do with my ITBs now?

There made by Wiseco!

ComeOnKip · 01-06-2007, 11:32 AM

Made by weisco but a different alloy. not the same piston (at all).
